    20W COB Spotlights - Dimmable?

    Thank you so much for commenting! @Dave_H - the 8-pin chip is marked '5305 1803' - see attached image, which does appear to be a LED boost driver. I thought too they would be buck-boost, given the wide input voltage. One of the things the images don't show, is the boards are held down with...

    20W COB Spotlights - Dimmable?

    Hi all! OK - I have four spotlights which use 20 watt COB LEDs, powered by a driver which accepts 10 - 30v input. I'm wondering if there is a way to make these dimmable, would a PWM dimmer work for example? I would attach a photo of the COB & driver board, but it seems I'm unable to do so...

    Tannoy Maglite - Rare?

    Not sure how rare this is - but thought I would mention it anyway for the collectors. I have a Maglite which was given to me some years ago by Tannoy - now for sale on eBay. Only a day to go - just type in Tannoy Maglite.

    Best MR16 LED to date?

    Thanks everyone for the replies and advice. Well I'm currently overhauling the craft so I guess the lighting can wait and I will see what happens with the technology. It's likely to be a year or so before she's back on the water so I'll have a look again at that time to see where we're at...

    Best MR16 LED to date?

    They don't need to be road legal as such - they are for use in a Hovercraft! The MR16s are for use in fittings which I already have installed. I have two either side at the moment - although I also have two spare so I could up to three each side to increase the light output. These are the...

    Best MR16 LED to date?

    Anymore thoughts anyone? I also just found these having done a bit more research: http://www.ledwaves.com/Delphi-MR-16-LED-Light-Bulb-6-Watt-5x-Nichia-083BT-LEDs-p-19702.html However - it would seem the average output of a 50W Halogen MR16 is anything from 900 - 5000 lumens depending on...

    Best MR16 LED to date?

    Hi everyone! Can anyone direct me to what is currently the brightest 12V MR16 LED at this time? I'm looking to replace four lights in a vehicle which currently has 50w halogen bulbs at present. Is there anything yet that comes close to a 50W Halogen MR16? Also being a vehicle the voltage can...
